BRUSH AND DUST' GUARD 2 Claims.

This invention relates to brush and dust-guard, and has for an object toprovide an attachment for a brush, especially for a floor-brush, which will retard the rising or drifting of dust raised by the brush in action.

A further object of the invention is to provide means for suspending about the edge of a brush, a. heavy fringe of such position and of such length as to drag upon the floor when the brush is moved, completely surrounding the brush and forming a dense wall of threads through which dust may not penetrate and in which dust will be retained.

A further object of the invention is to provide improved means for attaching said fringe to a brush.

A further object of the invention is to provide a covering made of sheet material, as for instance, a fabric which will completely enclose the brushhead and having its margin extended downwardly with a heavy fringe extended from the edge of the covered member of such type, position and proportion as to entirely enclose said brush, and of such material as to lend itself to washing, to relieve the fringe of the collected dust.

The invention, therefore, in its specific form, comprises an envelope so proportioned to t over and about the edges of the brush head and to extend downwardly to, or beyond the bottom,

which said brush-head has bristles extendedv downwardly therefrom, and said envelope having extended from its lower edge a fringe entirely surrounding said brush and of such length as to engage the floor upon which the brush is being employed and such texture and c'ompactness as to prevent dust from passing therethrough but to retain the dust within its interstices.

The drawing illustrates an embodiment of the invention and the views therein are as follows:

Figure 1 is a view in perspective of a brush with the dust guard applied thereto.

Figure 2 is a view in side elevation of a conventional floor brush, the fringe and envelope being broken away and shown in sections.

Figure 3 is a transverse sectional view through the brush, the envelope and the fringe as taken on line 3-3 of Figure 2.

Like characters of reference indicate corresponding parts throughout the several views.

The present invention is adapted to cooperate with brushes of various types but more practically with brushes designed for brushing and polishing floors and will be described in connection with such brushes but without limitation.

The brush of the type indicated as having a head Ill with bristles II and preferably weighted by means of applied weights I2, the brush forms no part of the present invention except in combination with the dust-guard and is subject to such variations as circumstances may make necessary or desirable. As shown, the brush is provided with two oppositely inclined threaded sockets I3 into which may be inserted a handle I4 having a threaded extremity I5 as is well known in the art.

The invention to be applied to this brush-head and bristles, comprises an envelope composed of substantially plain fabric I6, dimensions of which correspond substantially to the area of the brushhead, and having downwardly extending parts I1 which may be formed integral with the part I6 or applied thereto as found desirable. Preferably, at the down-turned part, two thicknesses of the fabric will be employed, and introduced between these two strips of fabric will be the heading I8 20 of the fringe I9. This fringe I9 is very heavy as to its texture and of such length as to engage a plane upon which the ends of the bristles rest. The heading may be secured in any approved manner but, preferably by stitches as shown at 2l). The downwardly turned parts I'I are so proportioned as to nt about the margin of the brushhead which under usual usage will maintain the dust-guard properly upon the head. However, additional means are shown, comprising a strip of material, as, for instance, a tape 2|, the ends of which may be tied as indicated at 22, and the tape will then be forced into the groove 23 common to most brush-heads. While this tape and tying means may be omitted without detracting seriously from the efficiency of the device, it will, at times, be found desirable to employ it, and provision is, therefore, made for such auxiliary means.

In operation, the brush will be operated by sliding along the floor, propelled through the handle I4 in the usual manner. It is well known that when so used, the brush raises the dust which is objectionable from many points of view. The present invention practically eliminates all dust from rising from point of operation, as it, by its fringe-like construction receives the dust into its own interstices, and being of such material as lends itself to washing, it may be washed and replaced as often as the use makes it necessary or desirable.

Of course, the brush and dust-guard herein illustrated may be modified and changed in various ways without departing from the invention herein set forth and hereinafter claimed.

I claim:-

1. The combination with a brush-head having a groove formed about its entire margin, of an envelope properly proportioned to flt and enclose the brush-head, ties secured to the envelope and adapted to compress the envelope into the groove of the head, and a fringe suspended from the edge of the envelope, said fringe comprising such plurality of threads as to form intervening dust re- 10 taining interstices.

2. 'Ihe combination with a brush-head having
